Patent number: 7950412Abstract: A toilet refill restrictor apparatus includes an adapter interposed between a fill valve and a refill hose. The adapter is non-removably coupled to the fill valve and is configured with a larger proximal pathway, and a smaller distal metering pathway for restricting the refill flow rate. The adapter may be coupled to a shortened horizontal outlet formed at a top portion of the fill valve. The horizontal outlet is shortened to a length such that the refill hose cannot be connected directly to the outlet. The adapter may also be coupled to a fill valve without a horizontal outlet where an exit port is defined in the vertical conduit of the fill valve. The adapter includes a securing mechanism to prevent removal from the fill valve without excessive force or breaking the adapter.Type: GrantFiled: October 25, 2006Date of Patent: May 31, 2011Assignee: Fluidmaster, Inc.Inventors: Jack Nguyen, Christopher Coppock

Patent number: 7900290Abstract: A dual flush refill device refills a bowl of a siphonic toilet with adequate supply of refill water in response to either a full or partial flush without wasting the refill water. The device provides a relatively high flow rate of refill water from a refill tube to an overflow tube in response to a partial flush, and a relatively low rate of refill water from the refill tube to the overflow tube in response to a full flush. As a result, the toilet bowl is refilled with a substantially similar volume of refill water regardless of which flush option is selected.Type: GrantFiled: February 9, 2006Date of Patent: March 8, 2011Assignee: Fluidmaster, Inc.Inventor: Joseph Han

Patent number: 7559337Abstract: A collapsible floating apparatus for controlling a valve includes a floating device and a collapsible lever. The collapsible lever includes a first member rotatably coupled to the valve, and a second member attached to the floating device at one end and rotatably coupled to the first member adjacent another end. The apparatus has a retracted position for shipping and storage, and operational positions. In the position, the second member, or the first and second members together, are brought adjacent to the valve. In operational positions, the first and second members act as a single lever to relay the buoyancy of the floating device drives to the valve. An adjusting member is provided for adjusting a relative position or angle between the first and second members, which in turn adjusts a water level.Type: GrantFiled: June 15, 2007Date of Patent: July 14, 2009Assignee: Fluidmaster, Inc.Inventor: Joseph Han
